Aldi is generally cheaper and has won the title of the UK's lowest-priced supermarket for several consecutive years, according to Which? research. While Lidl is a close second, usually costing only slightly more (an average of about £1.19–£1.99 more on a large basket), the two are extremely competitive, with many identical prices.
Aldi has been the cheapest supermarket every month since November 2023 and it was also the overall cheapest supermarket last year. However, Lidl is invariably close behind and is the second-cheapest supermarket every month, charging £1.99 more than Aldi, on average, across 2024.
Has Lidl replaced Aldi as UK's cheapest supermarket?
You've guessed it: Lidl. The findings show that based on a shopping list of 70 items, the total spent by standard Lidl shoppers was £120, while Aldi would set you back £121. It's the second time in 22 months that Lidl has taken the top spot after also being branded the cheapest supermarket in July 2025 as well.

Some customers also thought there should be a wider assortment of brands. Others had a few complaints about inconsistent service and items being out of stock. The common thread among some of the criticism seems to be that Lidl's merchandising mix is off.

It's called the "Aisle of Shame" (or "Aldi Finds") because shoppers often abandon their grocery lists and budgets to impulse buy delightful but unnecessary items like home goods, apparel, and seasonal gadgets found in the middle aisle, leading to a "shameful" amount of extras they didn't plan for, but it's an affectionate term for the store's addictive treasure hunt.

Aldi's checkout policy focuses on speed and efficiency, requiring customers to bag their own groceries, use a quarter for carts (returned later), and move items quickly from scanning to the bagging area, with cashiers scanning items very fast; some stores have self-checkout (often with item limits) or "Shop & Go" (app/contactless) options, but the core is customer participation to keep costs low.
